a couple of days ago i started ocing my fx-6300 which seemed pretty easy and i was 5hour prime stable @ 4.5 GHz and 1.352-1.360v. Yesterday i got a bsod while watching youtube video. I wasn't in mood to start solving anything so i presumed that its caused bu unstable oc, and since i was far from dangerous voltages, i just went one step higher. I was a bit surprised that cpu-z still was showing the same voltage. I added more, and more, until i had 1.35 set in bios, but cpu-z and other tools were showing same 1.352-1.36 (difference between bios setting and actual readings was bigger before). However, after having HWmonitor running for a while i noticed that voltage does go higher when under load. At the moment, running prime95, its 1.4v, jumping to 1.416 every few secs. The weirdest part is, that in the middle of prime test frequency went down to 1.4Ghz and voltage to 0.896 (can be seen in screenshot)
So is this behavior normal, or may i have missed some bios setting or smth? Voltage seems jumping way too much imo.
My bios settings are as close as possible to what was shown in this guide (bios is a bit different than mine)
Fx-6300 cooled by CM Hyper 212 evo
ASRock 970 Extreme3
8GB Kingston Beast 1866MHz
FSP Aurum Gold 700W
OCZ Vertex 4 128GB
Seagate Barracuda 1TB
I guess that BSOD at youtube wasn't related to cpu overclock, because i have other video related problems atm, like freezes and lags playing any video with any player. I will check drivers codecs and whatnot, but the question remains the same - is this voltage behavior normal/acceptable? Basically vcore is 0.05v higher than i set it in bios, and it jumps up and down as it likes. My girlfriend's system, which is basically the same (except HD7770, corsair CX500 psu, intel 330 ssd and no OC) and the voltage does not jump like that, and is only 0.01 v away from bios setting.
